DETROIT (AP) — Mazda is recalling its biggest SUV to fix suspension parts that can rust and come loose, causing a loss of steering control.

The recall covers more than 193,000 CX-9 SUVs in the U.S. from the 2007 through 2014 model years.

The company says in documents filed with U.S. safety regulators that front ball joints can rust from water leaks and separate from the suspension. Ball joints allow the wheels to pivot when the steering wheel is turned.

Dealers will replace the joints on both sides. When parts become available, owners of older vehicles in states where salt is used to clear roads in winter will get repairs first.

The recall comes after the National Highway Traffic Safety Administration opened an investigation into the problem in June. When the investigation was started, no crashes or injuries had been reported.
